What breast implant size is best for adding volume on top of breast for more cleavage as I am fuller on the bottom of breast?

Hello and thank you for your question. The size, shape, and profile of the implant is based on your desired breast size/shape, your chest wall measurements, and soft tissue quality.  This decision should be based on a detailed discussion with equal input from both you and your surgeon.  There are several advantages
and disadvantages to over vs under the muscle.  Under the muscle has the
advantage of lower capsular contracture rates, less risk of rippling, and
better visualization with future mammograms.  Most patients say that under
the muscle also has a more natural look and feel.  This entire surgery can be performed with a
small incision technique.  Make sure you specifically look at before
and after pictures of real patients who have had this surgery performed by your
surgeon and evaluate their results.   The
most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.

Dear kimmie7787,Upper pole fullness is achieved with appropriate implant selection but more importantly, submuscular placement, and precise pocket dissection. The submuscular placement allows the muscle to cover the top part of the implant which allows the upper pole to appear more full. Keeping away from the lateral chest during pocket dissection allows the implant to remain higher and prevents it from falling off to the side. Daniel Barrett, MD
